Oh what lovely speed....sometimes

Since getting back from holiday a few days ago and restarting the router (about 4 to 5 days???) I was getting this speed

From a sync of 3712 but about 10mins ago there was resync by the exchange to 3520

Heh ho such are the joys of Max ADSL and the wonderfull mix of copper & aluminium wiring we have.................................and what with all the BT Infinity adverts on the goggle box.......we do not exactly live in the sticks but no Infinity or ADSL2 here yet.!!!!!
